of this specification, and to the referencenumerals marked thereon.

The present. invention relates to stopmechanisms for machinery of all kinds and it has for an object to provide a construction which will be simple and effective in operation, inexpensive to manufacture and not liable to getout of order.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is it side view of a portion of a mangle for clothes or other wash goods to which my invention is shown applied; Fig; 2 is a detail vertical section of the mangle showing the feeding mecha- Fig. 3 is a sectional view in the direction of the axis of the driving and the driven element; Fig. 4 is a section on line a-a Fig. 3,; Fig. 5 is a section on line 71- same figure; and Fig. 6 is a section on line 0 -0 also of] same figure.

The invention is herein shown as applied to a mangle of the type embodying a large drum 1 with which cotiperates a, number 0 small rolls 2 (one only being shown), the goods being carried to the intake by a feeding mechanism comprising a series of belts or aprons 3 'driven from a roller 4. On the frame of the machine is journaled a. shaft- 5 which carries a worm 6 that meshes with a worm wheel 8 and on the shaft of the latter is a. gear 9 which drives a gear 10 that meshes with a pinion 11 having a sprocke 12 on its shaft to drive a chain 13 connecting with roller 4 to drive the feeding mechanism. The drum is driven by a gear 14 on the shaft of gear 10, said gear I l-being meshed with a large gear 15 that'turns with drum 1. In this instance the stop mechanism is controlled by a finger bo ard 16 that extends transversely of the feeding aprons and acts having a deflected end 28 as a tripping device as will be hereinafter pointed out. The stop mechanism comprises a driving and a driven element, the. driving element being preferably in the form of a sleeve 17 which surrounds shaft 5 and carries a pulley 18. while the driven element preferably comprises a disk 19 keyed mule. shaft 5 at 20.

Connection between the driven and the driving element is preferably efiected by a mechanism which may comprise a device 'such as a. pivoted pawl or dog 21 fixed on the pintle 22 which turns on the drivenelement and in this instance normally tending to move to establish connection, under the action of-a helical spring 23 or other device, said spring being secured at one end to thc disk 19 and having its other end connected to the dog 21 to swing the latter outwardly. This device 21 may eoiiperatewith any one of a series of stops 24 projecting from one face of a disk 25 that is keyed at 26 to the driving element. To hold the dog from engagement with stops or abutments 24, there may be employed a latch 27 which is preferably pivoted between its ends at 27 on the opposite side of the disk 19 of the driven element and has a laterally turned nose or shoulder 29 to cooperate with a nose or shoulder 30 projecting from pivot. 22 of device 21. After'the latch has released dog 21. said latch is held out of the path of the dog by the cooperation between shoulders 29 and 30, as shown in dotted lines in Figs. 5 and G.

The latch 27 may be operated to release dog 21 by a tripping mechanism which comprises preferahly a tripping lever 28 pivoted at 29 to a fixed part of the machine and normally lying out of the path of the deflected end of latch 27. For this purpose it is connected on the other side of its pivot by a link 30 with an arm of double armed lever 31 that is pivoted at 32 to'a fixed part and is actedon by a weight or other device in which power may be stored. In order to store power in the power device 33 and at the same time to control the device 21 to cause it to establish connection between the driving and the driven element, there is employed a means which may coliperate with that arm of the lever 31 up osite that which carries the weight. This means preferably comprises a arranged above the manually operable lever 34 turning on a an end of latch 27, thus releasing dog 21 to shaft 35 and having an arm 36 projecting permit the latter to cooperate with one of therefrom and enga ing lever 31. the stops 24 and establishing driving con- A fter the lever 31 lias been shifted to store nection between the driving and the driven power in weight 33, the lever is held in this element, the latch 27 being held out of the position by a latch 37 preferably in the form path of the dog by coiiperation between of a bell crank ant having a nose 38 which shoulders 29 and 30. The machine having cooperates with a projection 39 on the started will continue until the finger guard weight. The latch 31 is tripped by a trip or board 16 is shifted by an operator or the ping device which may comprise a pull bar usual belt is shifted from pulley 18 to loose 39 connected at one end to one arm of the pulley 54. When the latch 37 releases latch and at its other end to an arm 40 on weight 33, a cam 55 or other device which the shaft of the fin 'er board 16 which is may be. carried by trip 28 is shifted into ceding aprons so that the path of an arm 21' carried by dog 91 when an operator moves her hands too near causing the latter to be engaged and held so the intake machine, the belts ivill be against movementby latch 27 and breaking stopped as will be hereinafter pointed Outconneetion between the driving and the It is not desirable that the connection bedrivenelement. It will be noted that. the tween the drivin and the driven member be end 28 of lever 28 operates in a plane transestablished by t e movable dog 21, while verse to the axis of the driven member the driven member is stationary as'eithe'r it differ nt fro th plane of o rati of or the parts with which it oopera e fl cam 55.so -that the latch 27 will not be opliable to break.
